In this paper, we present results of a laboratory study in which participants completed an asynchronous collaborative search while thinking aloud. Based on analysis of the think-aloud data and screen recordings, we present a set of collaborative search actions and rationales that our participants employed. For each, we describe the purpose and motivations, and give illustrative examples. We also present three high-level strategies (individual, parallel, and divergent) that emerged from analysis of participantsí verbalizations and discuss how participants used these strategies as part of their overall search process. Our results show that collaboratorsí prior work influenced search strategies and behaviors, and that participants leveraged collaboratorsí work at various stages of the interaction including query formulation and results examination. We discuss how the observed behaviors complement existing models of interactive information seeking, and suggest ways to extend current models.
